To all whom-"it may concern:

Be itknown that I, FRANK B. BEIXKAMP, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and Statebf Ohio, haveinvented certainnew and useful Leg- Operated Tempo-Lever Attachments forPlayer-Pianos, of which the tollowingis a specification. My inventionrelates to means for operating the tempo lever of a player pian with theleg of the operator.

The object of my invention is to construct a device which will enable aperson to operate a player piano and control the tempo of same while hishands. are occupied in play ing another musical instrument such as acornet, mandolin, violimliute or any instrument which requires the useof the handsand arms to manipulate it.

My invention consists in a connection attached to a player piano adaptedto be operated by the leg of the operator to actuate the tempo lever ofthe player iano.

My invention also consists in the details of construction and; in theparts and combination and arrangements of parts as herein set forth andclaimed.

In the accompanying drawing, which serves to illustrate the constructionand use of my invention; Figure 1 is a perspective view of a portion ofthe keyboard of. a player pianoequipped with my invention.

Fig. 2 IS an end elevation o? a portion of a player piano showing theposition and manner of mounting my attachment. Fig. 3 is an enlargeddetail view of that portion of the" attachment which engages the tempolover of the player piano. Fig. 4 is a detail comprises a pivotallymounted supporting arm having a hollow extension adapted to receiveadyustahle tempo le er e g gscrew 15 ing member 9, said engaging memberbeing fastened to the hollow extension 8 by means of a set screw 10. Thetempo lever engagened and shortened as desired and is held.

at any desired length by means of a set At the other end offthe'telescopiciconnecting member 14 the leg engaging; yoke 16 is pivoted andheld by means of the thumb screw 17 and having prongs l8 adjusta-blymounted therein and held in position by means of set screws 19.

By means of the construction shown it is evident that the device may bereadily adjusted to accommodate. itself to any size person as well asany style or size of player piano, the tempo lever 4 being placed indifferent positions on difierent styles of player pianos.

My device will be found of inestimable value to singers who wish to playtheir own accompaniments upon player pianos, inasmuch as they areenabledto remain in a natural singing position and are not compelled to leanforward to operate the tempo lever with their hand.

It will thus be seen that this device enables a person to obtain anyvariation or not therefore wish to be confined to the exact constructionshown.
